Today's progress of degltal compression technology throw open the door to the new era of cable network. With this technology, the cable system comes to one of the best solution for the delivery of high-speed interactive servlces such as Internet access, Video-On-Demand (VOD) and telephony. The subscribers' dernand for the best media for the delivery of such servlces are growing rapldly, and Cable operators have ambitious plans to upgrade their existing networks or build new ones to satisfy the demand. The key factors that operators must consider when designing their networks are Scaiability. Reliability, and of course Cost. In this paper we analyse the upgr ading method of the existing networks to the reliable and scaiable architecture with minimal expense and disruption of sevices, and we introduce our new CATV equipment, that realize the future high-speed data communication via cable network in the cost-effective and reliable manner.
